NCT ID: NCT05671315 Recruiting - Chronic Hepatitis B Clinical Trials

A Prospective Study to Evaluate Peginterferon in Reducing the Incidence of HCC in CHB Patients

Start date: July 3, 2019
Phase: N/A
Study type: Interventional

China's new cases and deaths of hepatocellular carcinoma (HCC) rank first in the world. hepatocellular carcinoma is the third most morbid, second-most mortal malignancy in China. Up to 80% of hepatocellular carcinoma patients caused by HBV infection. Antiviral therapy can significantly reduce the incidence and mortality of hepatocellular carcinoma in patients with chronic hepatitis B (CHB), hinder the progression of liver disease, and effectively control the disease. However, studies in recent years have found that long-term therapy with Nucleos(t)ide analogue (NAs) cannot completely eliminate the risk of liver cancer in patients with chronic hepatitis B. In addition, a number of retrospective studies at home and abroad have shown that compared with long-term oral NAs, peginterferon can significantly reduce the risk of hepatocellular carcinoma in patients with chronic hepatitis B. However, there is limit prospective studies. This multicenter, randomized, open-label, controlled trial study is aim to evaluate the pegylated interferon alfa-2b injection in comparing to NAs in reducing the incidence of hepatocellular carcinoma, to provide evidences for new management and treatment strategy options for improving clinical outcomes for the chronic hepatitis B patients. About 267 chronic hepatitis patients with intermediate to high risk of liver cancer who are now receiving nucleoside therapy will be enrolled. Subjects will be randomized into the peginterferon combined NAs group and the NAs monotherapy group at a ratio of 2:1. Level of HBsAg, proportion of patients with HBsAg clearance and seroconversion, incidence of liver cirrhosis and hepatocellular carcinoma will be assessed.

NCT ID: NCT05669677 Active, not recruiting - NAFLD Clinical Trials

Study to Determine the Response to COVID-19 Vaccination and Prevalence of COVID-19 in Subjects With Chronic Liver Disease

Start date: March 15, 2023
Phase:
Study type: Observational

Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

NCT ID: NCT05661786 Recruiting - Chronic Hepatitis b Clinical Trials

Clinical Outcomes of HBeAg-negative CHB Patients With Indeterminate Phase

PILOT
Start date: December 2022
Phase:
Study type: Observational

Chronic hepatitis B virus (HBV) infection remains a global public health burden around the world. Investigating the disease process of chronic hepatitis B (CHB) is essential to individual management in clinical practice. According to American Association for the Study of Liver Diseases (AASLD) 2018 Hepatitis B Guidance, CHB can be classified into four phases: immune-tolerant CHB, HBeAg-positive immune active CHB, inactive CHB and hepatitis B e antigen (HBeAg)-negative immune active CHB. Antiviral therapy is recommended in patients with HBeAg-positive or -negative immune active CHB patients to reduce the incidence of liver cirrhosis and hepatocellular carcinoma, while periodic monitoring is recommended for inactive carrier and immune-tolerant CHB patients. However, a substantial proportion of patients fall into an indeterminate phase whose serum HBV DNA and alanine aminotransferase levels do not fit well into these well-described phases. Most of CHB patients with indeterminate phase are HBeAg negative. However, the clinical outcomes of these patients remain unclear. Therefore, the purpose of this study is to investigate the clinical outcomes of HBeAg-negative chronic hepatitis B patients with indeterminate phase.
